FP16 yes 144k 7397.3-8816 t/s ~324.4-386.7 (slow)
Q8 yes 145k 14794.7-17632 t/s ~648.9-773.3 (slow)
Q4 yes 145k 26419-31485.7 t/s ~1158.7-1381 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA GeForce RTX 3080 Ti run MegaMolBART?โ–ถ

Yes. At Q4 it generates ~26419-31485.7 tok/s and fits up to 145k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1158.7-1381 tok/s.

How much context fits?โ–ถ

At Q4, up to about 145k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
